150W 8 Ohm High-Performance Loudspeaker
S5T - 8-ohm or 70V - 32W/16W/8W/4W/2W/1W S4T - 8-ohm or 70V -16W/8W/4W/2W/1 W IMPORTANT: When connecting to a 70V amplifier, make sure that the Tap Selector is not in the "8Q" position. Tap Selection Indicator (S5T Tap shown) Strip about 1/2" of insulation from the wires. Push down on the spring damps, and insert the wire into the hole, then release the clamp. To ensure proper polarity, wire black terminals to black terminals and red terminals to red terminals on the same speaker run. When designing a 70V system, the total of all power tap settings of al! the connected speakers CANNOT EXCEED the output power of the 70V amplifier (amplifier power can exceed the sum of the speaker loads). 70V (+) 16W Tap 3ZW Tap . 8W Tap 8W Tap 18W Tap EXAMPLE: 16+ 32 +8+8+16= 80 Watts minimum ampiifier output power rating. Low-impedance System Configurations When wiring together multiple NEAR Signature speakers set to 8 ohms, it is important to calculate (using Ohm's Law) the total load that these speakers present to the amplifier. The total load impedance of the interconnected speakers cannot be lower than the minimum load impedance rating of the low-impedance amplifier. Also care must be taken to ensure the amplifier cannot overdrive the speaker's max power rating. Low-lmpedance Amplifier ]--4n TOTAL--] sn an i, ^00 -EP + ? + 1 IIGh -4aTOTAL- sft sn + -8- + 4. EXAIVIPL.E: Two 80 speakers in parallel = 4Q. The amplifier must be rated to work into 4Q loads. Also in this example, the max amplifier output power rating (each channel into 4Q) should not exceed 1 SOW for S4/T (2 X 75W) speakers or 300 for S5/T (2 X 1 SOW). Secure Mounting Base (A) to wall as shown. SMPORTANT: THE WALL MATERIAL AND USER SUPPLIED ATTACHMENT HARDWARE MUST BE ABLE TO RESIST A PULL OUT FORCE OF AT LEAST 10X THE WE8GHT OF THE SPEAKER. 2. Determine the desired orientation (horizontal or vertical) for the speaker. Attach the Mounting Cup Bracket (B) to the indentation (C) on the back of the speaker enclosure using the two supplied M5 screws as shown. VERTICAL MOUNT HORIZONTAL MOUNT 3- Connect the speaker wires to the rear input terminals on the loudspeaker. Set the speaker with Mounting Cup Bracket (B) over the Mounting Base (A). Loosely screw the Mounting Cap Nut (D) onto the Mounting Base threaded stud. Aim the speaker and then firmly tighten the Mounting Cap Nut (D) with a 1/2" nut driver or socket wrench. Be carefui not to over-tighten. VERTICAL MOUNT (Speaker Rear) 1 Safety Cable Attachment Point Safety Cable Attachment Point The NEAR Signature speakers provide an attachment point for a user-suppiied safety cable. The other end of the safety cable must be attached to a a user-supplied anchor independent of the speaker mounting hardware. Ail hardware, including the cable, must be rated to withstand a force 10X greater than the weight of the speaker. Care & Maintenance If needed, you may clean the speaker cabinet by using only soap and water with a soft cloth to wipe gently. HORiZONTAL (^^ MOUNTRICOH MP C3503 RICOH MP C3503
